https://bugzilla.kernel.org/show_bug.cgi?id=100671 --- Comment #2 from Lidong Chen <jemmy858585@xxxxxxxxx> --- When does the write error happen and what guest/host are you running ? this error happen when the guest os is booting. the guest os kernel verison is also 4.1.0+. If it's a regression, would it be possible for you to bisect it ? yes,the old kernel version didn't have the bug. so i will try to find out which patch cause this error. Is bug 100661 related to the same hardware ? yes. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
